How can you solve 6+4/5B=9/10b
faltersainse [42]
6+\frac{4}{5}b=\frac{9}{10}b \ \ \ |-\frac{4}{5}b \\ \\
6=\frac{9}{10}b-\frac{4}{5}b \\ \\
6=\frac{9}{10}b-\frac{8}{10}b \\ \\
6=\frac{9-8}{10}b \\ \\
6=\frac{1}{10}b \ \ \ |\times 10 \\ \\
b=60

Question 4 (1 point)
igomit [66]

Answer:

x = 15

Step-by-step explanation:

We want to solve for x in  3*(2x + 5) = 3x + 4x

First simplify.

3*(2x + 5) = 7x

Next, distribute the 3.

3*2x + 3*5 = 7x

6x + 15 = 7x

15 = 7x - 6x

15 = x

Solve for y.
kenny6666 [7]

Answer:

y=−1/7

for the picture is y=-57/7

Step-by-step explanation:

<h3>1. 8= -7y +7</h3>

Switch:sides

-7y+7=8

subtract 7 from both sides

-7y=1

divide both sides by -7

y=−1/7

<h3>2.so for 8/y+7=-7</h3>

multiply both sides by (y+7)

8/y+7(y+7)=-7(y+7)

simplify 8=-7(y+7)

flip

-7(y+7)=8

divide both sides by -7

y+7=-8/7

subtract 7 from both sides

and simplify

y=-57/7
