Question

:)

Answer 1

Two simultaneous equations in two unknowns.
To solve for x and y try the elimination method or the substitution method.

Answer 2

Substitution method: From second equation find x. x = 2 + 3y. Put this in the first equation and solve for y. Then solve for x.

Answer 3

Elimination method: Multiply second equation by -10 and add it to the first equation to eliminate y. Solve for x and then solve for y.

Answer 4

Not like that. Find x from the SECOND equation.

11x − 30y = 25 ---- (1)
x−3y = 2 ---- (2)

From (2): x = 2 + 3y
Put this in (1)

11(2 + 3y) - 30y = 25
22 + 33y - 30 y = 25
3y = 25 - 22 = 3
y = 1

Put y = 1 in (2):
x - 3(1) = 2
x = 5.

x = 5, y = 1.
