Answer:
<h2>y = 9</h2>
Step-by-step explanation:
Put x = 5 to the equation -6x - 3y = -57
(-6)(5) - 3y = -57
-30 - 3y = -57 <em>add 30 to both sides</em>
-3y = -27 <em>divide both sides by (-3)</em>
y = 9
Answer:
w = 13 m
l = 32
Step-by-step explanation:
let 'w' = width
let '2w+6' = length
P = 2l + 2w
90 = 2(2w+6) + 2w
90 = 4w + 12 + 2w
90 = 6w + 12
78 = 6w
w = 13
length = 2(13) + 6 → 32
l = 32
check:
2(13) + 2(32) should equal 90
26 + 64 = 90
90 = 90 checks out
