Topic- writing equations in one variable.

Five and a number is equal to fifty- three.

2x+4-3

Step-by-step explanation:

answer: a numerical coefficient is a constant multiplier of the variables in a term. in the term -5x2y, the numerical coefficient is -5. in the expression ax2 + bx + c, the numerical coefficient of the x2 term is "a" and the numerical coefficient of the x term is "b".

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
