Solve 2x+2x+3x/2+2^2=90^circ

$$\frac { 2 x + 2 x + 3 x } { 2 } + 2 ^ { 2 } = 90 ^ { \circ }$$

Solve for x

$$x = \frac{172}{7} = 24\frac{4}{7} \approx 24.571428571$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 2.

$$2x+2x+3x+2\times 2^{2}=180$$

To multiply powers of the same base, add their exponents. Add 1 and 2 to get 3.

$$2x+2x+3x+2^{3}=180$$

Combine 2x and 2x to get 4x.

$$4x+3x+2^{3}=180$$

Combine 4x and 3x to get 7x.

$$7x+2^{3}=180$$

Calculate 2 to the power of 3 and get 8.

$$7x+8=180$$

Subtract 8 from both sides.

$$7x=180-8$$

Subtract 8 from 180 to get 172.

$$7x=172$$

Divide both sides by 7.

$$x=\frac{172}{7}$$
