Question

9(4–5x)+2=7(6x–7) plz help!!

Answer 1

Answer:

$x=1$

Step-by-step explanation:

So we have:

$9(4-5x)+2=7(6x-7)$

First, distribute the left:

$36-45x+2=7(6x-7)$

Now, distribute the right:

$36-45x+2=42x-49$

Add the numbers on the left:

$38-45x=42x-49$

Add 49 to both sides. The right cancels:"

$87-45x=42x$

Add 45 to both sides:

$87=87x$

Divide both sides by 87:

$x=1$

And we're done!

Answer 2

Answer:

x=1

Step-by-step explanation:

9(4–5x)+2=7(6x–7)

Distribute

36 -45x +2 = 42x-49

Combine like terms

-45x +38 = 42x-49

Add 45x to each side

-45x +38 +45x = 42x+45x-49

38 = 87x-49

Add 49 to each side

38+49 = 87x-49+49

87 = 87x

Divide by 87

87/87 = 87x/87

1 =x
