1=(0.075*0.90)+(0.065*1)+(x*1.50)

Solution for 1=(0.075*0.90)+(0.065*1)+(x*1.50) equation:

Simplifying
1 = (0.075 * 0.90) + (0.065 * 1) + (x * 1.50)

Multiply 0.075 * 0.90
1 = (0.0675) + (0.065 * 1) + (x * 1.50)
1 = 0.0675 + (0.065 * 1) + (x * 1.50)

Multiply 0.065 * 1
1 = 0.0675 + (0.065) + (x * 1.50)
1 = 0.0675 + 0.065 + (x * 1.50)

Reorder the terms for easier multiplication:
1 = 0.0675 + 0.065 + (1.50x)

Combine like terms: 0.0675 + 0.065 = 0.1325
1 = 0.1325 + (1.50x)

Solving
1 = 0.1325 + (1.50x)

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '(-1.50x)' to each side of the equation.
1 + (-1.50x) = 0.1325 + (1.50x) + (-1.50x)

Combine like terms: (1.50x) + (-1.50x) = 0.00
1 + (-1.50x) = 0.1325 + 0.00
1 + (-1.50x) = 0.1325

Add '-1' to each side of the equation.
1 + -1 + (-1.50x) = 0.1325 + -1

Combine like terms: 1 + -1 = 0
0 + (-1.50x) = 0.1325 + -1
(-1.50x) = 0.1325 + -1

Combine like terms: 0.1325 + -1 = -0.8675
(-1.50x) = -0.8675

Divide each side by '-1.50'.
x = 0.5783333333

Simplifying
x = 0.5783333333
