19+12=x+5*z

Answer:

X = -5Z + 31

Step-by-step explanation:

Subtract 5Z5Z from both sides.

19 - 5Z = X - 12

19 − 5Z = X − 12

2 Add 1212 to both sides.

19 - 5Z + 12= X

19 − 5Z + 12= X

3 Simplify 19-5Z+1219−5Z+12 to -5Z+31−5Z+31.

-5Z + 31 = X

−5Z + 31 = X

4 Switch sides.

X = -5Z + 31

X = −5Z + 31
