3(x + 2) + 4(x - 5) = 10
Use the distributive property:
3x + 6 + 4x - 20 = 10
Combine like terms:
7x -14 = 10
Add 14 to both sides:
7x = 24
Divide both sides by 7:
x = 24/7
Answer:
-6
Step-by-step explanation:
The notation a23 refers to the element in row 2, column 3. That element is -6.
I believe it is {sqr(1/8)/2} or 0.5*sqr(1/8)
X=3 because you have to isolate the variable by dividing each side by factors that don’t contain the variable .
