Question

A set of equations is given below:

Equation A: g = 4h + 1
Equation B: g = 3h + 5

Which of the following is a step that can be used to find the solution to the set of equations?

4h + 5 = 3h + 1
4h + 1 = 3h + 5
4h = 3h + 5
4h + 1 = 3h

Answer 1

can you help me please

Answer 2

both equations are equal to g

to that means that you can write them with

the right side of equation A equal to the right side of equation B

hope it helps

Answer 3

can you help with this one too

Rachel is 11 years older than Scott. Rachel's age is 7 years less than two times Scott's age. The system below models the relationship between Rachel's age (r) and Scott's age (s):

r = s + 11
r = 2s – 7

Which is the correct method to find Rachel's and Scott's ages?

Solve r + 11 = 2r – 7 to find the value of s.
Solve s + 11 = 2s – 7 to find the value of s.
Write the points where the graphs of the equations intersect the x-axis.
Write the points where the graphs of the equations intersect the y-axis.

Answer 4

same thing, they are both equal to r

so right side of equation 1 is equal to right side of equation 2

Answer 5

you may also tell you teacher that you can't find where the graphs intersect the x-axis or y-axis

as the equations are written in terms of r and s

Answer 6

i don't get what the answer will be
