x=5

b=6

v=3

Step-by-step explanation: so what you want is to get the variable on one side of the =. So that means you have to cancel out the number next to the variable to isolate the variable. so for the first problem ,x+2=7 you will subtract 2 from 2 and subtract 2 from 7 which equals 5. for the next problem you will add 5 to both sides, the last problem divide by 4 on both sides.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

first one because it can't have a fraction in it
