Question 527186
2/3x + 3/4x = -17
.
One way to decide on the common denominator is to multiply them.
3*4 = 12.
So, you need to convert both fractions to 12ths.
.
2/3 * 4/4 = 8/12
3/4 * 3/3 = 9/12
.
8/12*x + 9/12*x = -17
.
17/12*x = -17
.
Multiply both sides by 12 to eliminate the fraction.
.
17x = -17*12
.
divide both sides by 17
.
x = -12
.
