Answer:
Step-by-step explanation:
2x+5x+3=0
7x+3=0
-3 -3
=0 =-3
7x=-3
-3/7=-0.42857142857
x=-0.42857142857
I think it is right
2 step equations are equations that require 2 steps to solve it.
For example, 2x + 5 = 3x + 6
To solve for x, we must isolate it.
First subtract 2x on both sides, which is ONE step.
2x + 5 = 3x + 6
-2x -2x
5 = x + 6
The we must subtract 6 from both sides of the equation, which makes is the second step.
5 = x + 6
-6 -6
-1 = x
-1 would be the answer and we only used 2 steps to solve it.
Answer:
Step-by-step explanation:
3x+5y=11 answer : 3x+5y-11=0
Step by step explanation:
3x+5y=11
Move the constant to the left
3x+5y-11=11-11
Eliminate the opposite
3x+5y=11
5y+8y
