Answer:
7x-20=2x-3(3x+2)
We move all terms to the left:
7x-20-(2x-3(3x+2))=0
We calculate terms in parentheses: -(2x-3(3x+2)), so:
2x-3(3x+2)
We multiply parentheses
2x-9x-6
We add all the numbers together, and all the variables
-7x-6
Back to the equation:
-(-7x-6)
We get rid of parentheses
7x+7x+6-20=0
We add all the numbers together, and all the variables
14x-14=0
We move all terms containing x to the left, all other terms to the right
14x=14
x=14/14
x=1

Answer:
y = 2x +3/2
Step-by-step explanation:
y = mx + b
m is the slope so
y = 2x + b
b is intercept so
y = 2x +3/2
The fraction 2/5 added by 3/4 will be 1 3/20.
<h3>How to calculate the fraction?</h3>
A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers. On the other hand, a fraction appears in the numerator or the denominator of a complex fraction.
The fraction will be illustrated thus:
=✓2/5 + 3/4
= 8/20 + 15/20
= 23/20
= 1 3/20
The value is 1 3/20.
