How do you solve 2.2x - 5= 2( 1.4x + 3)?
1 Answer
Explanation:
Use order of operations (PEMDAS).
-
Solve inside parentheses first. Since
(1.4x+3) cannot be simplified any more, skip this step. -
There are no exponents, so skip this step.
-
Multiply
2(1.4x+3) by distributing the2 . There is no division, so do not worry about dividing anything.
2.2x - 5= color(red)(2(1.4x + 3))
2.2x - 5= color(red)(2(1.4x)+2(3))
2.2x - 5= color(red)(2.8x+6) -
Since we cannot simplify the equation by adding or subtracting, skip this step.
-
Isolate and solve for
x .
color(red)(-0.6x)-5=6
-0.6x=color(red)11
x=-11/0.6=-18.33
EXTRA STEP: If your teacher wants the answer in fraction form, technically
