Question

I have one more row of the same thing if anyone is willing to help me with them again

Thank you!!
Solve the equation for the indicated variable.

Answer 1

d = 21-e/c j = h/ 15 and f = hg +7

Explanation:

the first step is to rearrange the first equation in other to find d

21 = cd + e

21- e = cd

d = 21-e/c

we will also follow the same step by rearranging the second equation in other to find j

h/j = 15

multiply through by j, we have

j * h/j = 15 * j

so j cancels out j and we have 15 having a j

h = 15j

divide through the above equation by 15

j = h/15

We Will do the same by rearranging the third equation and also In other to get our f

f- 7 = h

g

recall that h = 15j
