There are no parentheses or exponents, so the Order of Operations tells you to start by performing division and multiplication left to right.
7-3+4÷2×6
= 7-3+2×6
= 7-3+12
After you have done that, you perform addition and subtraction left to right.
= 4 +12
= 16

Answer: 77
Step-by-step explanation:
8(4x+5)=136
Multiply the number outside of the parenthesis(8) with the numbers inside the parenthesis(4x and 5).
32x+40=136
Subtract 40 from both sides
32x=96
Divide both sides by 32 so the only thing remaining on the side of the variable is only the variable itself.
Final Answer: x= 3
Answer:
x = 1.53, -1.53.
Step-by-step explanation:
9x^2 - 21 = 0
9x^2 = 21
x^2 = 21/9
x = +/- √21 / 3
x = 1.53, -1.53.
