First, solve for x. Isolate the x. Do the opposite of PEMDAS.
2x + 4 = 8
Note the equal sign. What you do to one side, you do to the other.
subtract 4 from both sides
2x + 4 (-4) = 8 (-4)
2x = 8 - 4
2x = 4
divide 2 from both sides
2x/2 = 4/2
x = 4/2
x = 2
you know you're starting number now: 2
"then add it to two": 2 + 2 = 4
"then add it to ten": 4 + 10 = 14
"then subtract three": 14 - 3 = 11
"then add ten": 11 + 10 = 21
21 is your final answer

So, 11 = 7 + 2^2;
19 = 11 + 2^3;
35 = 19 + 2^4;
35 + 2^5 = 35 + 32 = 67 is the next number in the series 7, 11, 19, 35, ...
Answer:
3x + y = 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
3x + y = - 12 ( subtract 3x from both sides )
y = - 3x - 12 ← in slope- intercept form
with slope m = - 3
• Parallel lines have equal slopes , then
y = - 3x + c ← is the partial equation
to find c substitute (- 1, 5 ) into the partial equation
5 = 3 + c ⇒ c = 5 - 3 = 2
y = - 3x + 2 ← equation in slope- intercept form
add 3x to both sides )
3x + y = 2 ← equation in standard form
