Answer:
x = 14
Step-by-step explanation:
Step 1: First, Simplify the fraction.

Step 2: Next, Multiply both sides by 7.
4x = 8 × 7
Step 3: Simplify 8 × 7 to 56.
4x = 56
Step 4: Then, Divide both sides by 4.

Step 5: Lastly, Simplify the fraction and you're done!
x = 14
Answer:
19(42 + 58)
Step-by-step explanation:
Assuming x = multiply, you are trying to solve the distributive property. Divide common factors from both terms (in this case 19).

True! they are corresponding angles.
[(21 + 6) − 3^2] ÷ 9 ⋅ 2=[(27) − 9] ÷ 9 ⋅ 2
=18 ÷ 9 ⋅ 2
= 2 . 2
= 4
