Answer 1

do you know how to solve this using substitution or elimination method?

Answer 2

wouldnt you substitute the number in like 4(-3) - 3(0) ?

Answer 3

well yeah you could do that for each choices and check whether that choice satisfy the equations. would you like to apply that instead of solving it?

Answer 4

Yea. Can I do it then check back with you to see if my answer is correct?

Answer 5

It doesnt seem like any of those choices work

Answer 6

Solving both equations:
A) 4x - 3y = 26
B) 3x + 2y = 11
Multiply equation B by 1.5
B) 4.5x + 3y = 16.50 Then add this to A)
A) 4x - 3y = 26

8.5x = 42.5
x = ??

@wolf1728 could you help with another?

Answer 9

Well okay.

Answer 10

A line has a slope of -6 that passes through the point (-12, 5). What is the equation of the line?
(Points : 4)
6x + y = -77

6x + y = -67

-6x + y = 77

-6x + y = 17

Answer 11

b = y -m*x
b = 5 -(-6*-12)
b = 5 -72
b = -67
y = -6x -67

So looks like answer is
6x + y = -67

Answer 12

thank you
