Answer:
It is higher I have no time to explain. Hope it's right!
8z − 4 = 7z
move 8z to the other side
sign changes from +8z to -8z
8z-8z-4=7z-8z
-4= 7z-8z
-4= -z
mutiply both sides by -1 to get +z
(-4)(-1)= (-z)(-1)
Answer:
z= 4
Answer:
solve the inequality as if it was a normal equal sign
Multiplying Fractions Three simple steps are required to multiply two fractions: Step 1: Multiply the numerators from each fraction by each other (the numbers on top). The result is the numerator of the answer. Step 2: Multiply the denominators of each fraction by each other (the numbers on the bottom). The result is the denominator of the answer. Step 3: Simplify or reduce the answer. Examples of multiplying fractions:
