Answer:
x = 1
Step-by-step explanation:
0.5x-0.3=0.2
1. Multiply both sides by 10.
0.5x*10-0.3*10=0.2*10
2. Refine.
5x-3=2
3. Add 3 to both sides.
5x-3+3=2+3
4. Simplify.
5x=5
5. Divide both sides by 5.
5x/5=5/5
6. Simplify.
x=1
Answer:
m=5
Step-by-step explanation:
We can solve this by using a system of equations. The easiest way to solve this is by using substitution.
3m=19-n Subtract both sides by 19 to find n.
<u>-19 -19</u>
3m-19=-n Divide everything by -1 to make n positive.
<u>/-1 /-1</u>
n=-3m+19
Now, we can substitute n into the second equation.
2m+5(-3m+19)=30 Substitute (-3m+19) into n.
2m-15m+95=30 Simplify.
-13m+95=30 Simplify and subtract both sides by 95.
<u>-95 -95</u>
-13m=-65 Divide both sides by -13.
<u>/-13 /-13</u>
m=5
We don't need to solve for n at all, so that is the answer!
Hope this helps, and have an amazing day ♥
