Question

Solve the equation -4(2-1.2x) = 40 Solve the equation 9=6y+33

Answer 1

For the first one x=10 and for the second one y=-4

Answer 2

Answer:

x = 10

y = -4

Step-by-step explanation:

$\ -4(2 - 1.2x ) = 40\\\ -8 + 4.8x = 40\\\ 4.8x = 40+8\\\ 4.8x = 48\\x = \frac{48}{4.8} = \frac{48 \times 10}{48} = 10$

$9 = 6y + 33\\6y = 9 -33\\6y = -24\\y = -4$
