-3(3x+y=19)
4x+3y=26

-9x-3y=-57
4x+3y=26

-5x=-31
x=6.2 substitute x into the equation:

3(6.2)+y=19
18.6+y=19
y=.4

(6.2,.40)

(16+3)-10÷5×3^2? with explanation step by step
NemiM [27]
(16+3)-10\div5\times3^2\text{ = 1}

Here, we want to simplify the given expression

We shall use the order of simplification for this

The order is PEDMAS

We shall start with the terms in parentheses before we move to the exponents

We have;

\begin{gathered} (16+3)-10\div5\times3^2 \\ =\text{ 19-10}\div5\times3^2 \end{gathered}

Next is the exponent

=\text{ 19-10}\div5\times9

The next thing to do is to divide

=\text{ 19-}2\times9

The next thing to do is to multiply

=\text{ 19-18}

We then proceed to subtract;

=\text{ 19-18 = 1}

Solve using factoring
jolli1 [7]
The equation is balanced by the 3's on both sides so that cancels out. we are left with:
x^2-6x=0
we take out an x, leaving us with:
x(x-6)=0
we know that to find the solution [ or "zero's", ] we must set "x"=0, and "x-6"=0.
the solutions are: x=0 and 6.
hope that helped, xx
