Solve for y.<br><br> −140=18+4(5y−2)
vagabundo [1.1K]

For this case we have the following equation:

-140 = 18 + 4 (5y-2)

From here, we must clear the value of y.

For this, we follow the following steps:

1) Distributive property:

-140 = 18 + 20y-8

2) Variable terms on one side of the equation and constant terms on the other side of the equation:

20y = -140 - 18 + 8

3) Algebraically add the constant terms:

20y = -150

4) Pass the number 20 to divide:

y = -\frac{150}{20}\\y = -7.5

Answer:

The value of y is given by:

y = -7.5

3) k(a)= a + 4; Find K(0) ; k(2x - 7)
Westkost [7]

Answer: k(0) = 4; k (2x - 7) = 2x -3

Step-by-step explanation:

If k(a) = a + 4

K(0) will be 0 + 4

K(0)= 4

Then, k (2x - 7) = 2x -7 +4

K (2x - 7) = 2x - 3
