Answer:
x = -1.9
Explanation:
Finding the value of 'x':
3(4x - 9) + 10 = 15x + 2 + 7x
3*4x - 3*9 + 10 = 15x + 7x + 2 {Distributive property}
Add the like terms on the RHS and add the constants on the LHS.
12x - 27 + 10 = 15x + 7x + 2
12x - 17 = 22x + 2
Subtract 12x from both sides,
-17 = 22x + 2 -12x
-17 = 10x + 2
Subtract 2 from both sides,
-17 -2 = 10x
-19 = 10x
Divide both sides by 10,
x = -19 ÷ 10
x = -1.9
