Its -5z+6 sorry if its wrong

Step-by-step explanation:

-1/4 x 4 (5x+6)

-(5x+6)

= -5x-6

The answer is -5x-6

Equation 1  ⇒ x + 3y = 7equation 2  ⇒ 2x + 4y = 8isolating x in equation 1x + 3y = 7  x = 7 - 3ysubstitute x = 7 - 3y into equation 22x + 4y = 82(7 - 3y) + 4y = 8then solving 'y'14 - 6y + 4y = 814 - 2y = 814 - 8 = 2y6 = 2yy =  ⁶/₂y = 3substitute y = 3 into equation 1x + 3y = 7x + 3(3) = 7x + 9 = 7x = 7 - 9x = -2the solution (x, y) is (3, -2)
