Question

Solve using the given method
substitution
3x+2y=12
y=2x-1

Answer 1

x=2 and y=3

Explanation:

solve from the first variable in one equations, then substitute the result into another equation.

Answer 2

Substitute y = 2x - 1 into 3x + 2y = 12

7x -2 = 12

Solve for x in 7x - 2 = 12

x = 2

Substitute x = 2 into y = 2x - 1

y = 3

Therefore,

x = 2

y = 3
