Answer:

x = -8 and x = 3

Step-by-step explanation:

Split the equation into 2 possible cases:

2x + 5 = 11

2x + 5 = -11

Then, solve these 2 equations.

2x + 5 = 11

2x = 6

x = 3

2x + 5 = -11

2x = -16

x = -8

So, the 2 solutions are x = -8 and x = 3

Solve the equation 3x + 5y = 15 for y

Nana76 [90]

We are given this equation :

$3x + 5y =15$

We have to solve it for y, so we need to isolate y on the left side,

first we have 3x on the left side in addition, so when we take it to the right side we apply opposite operation that is subtract 3x

$5y =15-3x$

Next y is in multiplication with 5, so we apply opposite operation of multiplication that is division, so dividing right side by 5

$y=\frac{15-3x}{5}$
