Hello!!! Princess Sakura here ^^
Step-by-step explanation:
When you combine like terms you see the ones that are similar then you add or subtract, depends on what the signs are. For this one -7x is similar to x so in this case you would add x to the -7x which will give you -6x.
False, because a^2+b^2=c^2 and no matter what numbers substitute for which ever variable the answer isn’t going to be true
To solve this, you need to cross multiply the fractions.
Let’s say you have these fractions:
A / B = C / D
To cross multiply, multiply the denominator of the first fraction (B) by the numerator of the second fraction (C). Multiply the numerator of the first fraction (A) by the denominator of the second fraction (D).
You get B x C = A x D
After cross multiplying your fractions, you get 63 = 7(c +4)
Distributing the 7 into c+4 gives you this:
63 = 7c + 28
Now solve this like a normal equation with a variable
63 = 7c + 28
35 = 7c
5 = c
To double check that, plug c = 5 into the original equation.
1/(5) + 4 = 7/63
1/9 = 7/63
7/63 simplifies into 1/9 (7:7 = 1, 63/7 = 9)
1/9 = 1/9 so c = 5 is correct
