ANSWER WITH STEPS:
Let's solve for x.
5x−10y=−5
Step 1: Add 10y to both sides.
5x−10y+10y=−5+10y
5x=10y−5
Step 2: Divide both sides by 5.
5x
5
=
10y−5
5
x=2y−1

units²
Answer:
The solution to this question is 39
Step-by-step explanation:
Given that :
√(3x+7)+2√(x-8)=0.
√(3x+7)=-2√(x-8) (i)
square of the equation (i)
Then
(√(3x+7))^2=(-2√(x-8))^2
we know that √a*√a=(√a)^2=a So,
(3x+7)=4(x-8)
3x+7=4x-32 //multiply by 4
32+7=4x-3x exchange the value.
39=1x
x=39.
