Examples of substitution property?
4a-2 (if a=3) 4•3-2 12-2 10......so 4a-2=10
Solve the following equation 2A3 equals 8 plus 4A?
Solve the following equation for A : 2A/3 = 8 + 4A
What is 3a x a?
3a2
X over 2 equals x over 5 plus 1?
x/2 = x/5 + 1 5x = 2x + 10 3x = 10 x = 3 1/3
What is the value of x in the equation 3 over 4x plus 2 equals 5 over 4x-6?
If the questions asks: (3)/(4x+2) = (5)/(4x-6) then x = -(7/4)
4a-3 when a equals 2?
5
How do you solve 4a-2 equals 7a-6?
4a-2=7a-6 4=3a a=4/3
4a plus 3-a equals 12?
4a+3-a =12 4a-a = 12-3 3a = 9 a = 3
What is the answer to 4a - 5 equals 7a - 7?
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
What is 4 x a x 3 equals?
4a x 3
What is 2A times 3 equals 8 plus 4A?
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
What is the answer to 4a-3 equals 2a plus 7?
a=5
2 over 3 equals what over 12?
2 over 3 equals 8 over 12
When 3a2-2a plus 5 subtracted by a2 plus a equals 1?
Not sure why it is 3a2- if you mean 3*a*2, then: 3*a*2=6a (6a-2a)+5-2(a (or a2)+a)=1 4a+5-(2a+a)=1 4a+5-2a-a=1 Then take the 5 over (remember, the +5 become -5 when transposed): 4a-2a-a=1-5 Solving the equations on both sides gives: a=-4 Is this your answer?
Solve this equation using addition method 4a subtract 5b equals 7 and 4a plus 5b equals 17?
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
What is 4a plus 3 when a equals 3?
4a+3 when a=34(3)+312+3=15So you are substituting(replacing) 'a' with the known value of '3'. You then multiply the '4' with the '3' because of the placing of 'a'.
What does 2 over 3 equal to?
