Hi, Hope I can help,
.
how can you solve +2x=10+?
.
"2x" is equal to one number, to find "x", we will have to separate the "2" and the "x"
.
+2x+=+%282%29%28x%29+
.
+%282%29%28x%29=10+, to find "x", we will get rid of the "2" by dividing each side by "2"
.
+%282%29%28x%29=10+ = +%28%282%29%28x%29%29%2F2=10%2F2+ = +%28%282%29%28x%29%29%2F2=5+, the "2" will cross out on the left side
.
+%28cross%282%29%28x%29%29%2Fcross%282%29=5+ = +x+=+5+, you can check by replacing "x" with "5" in the equation
.
+2x=10+ = +2%285%29=10+ = +10+=+10+ (True)
.
+x+=+5+
.
