Question

`y=4x-22\\\\2x+3y=4`

Solve the system of equations above using the method of your choosing.

Answer 1

• (5, - 2)

-------------------------

Given system:

• y = 4x - 22
• 2x + 3y = 4

Solve it by substitution:

• 2x + 3(4x - 22) = 4
• 2x + 12x - 66 = 4
• 14x = 4 + 66
• 14x = 70
• x = 5

Find y:

• y = 4*5 - 22
• y = 20 - 22
• y = - 2
