You can put this solution on YOUR website!
J = Jennifer's age now
S = Sue's age now
J+=+S+%2B+6
J+%2B+4+=+2%28S+-+5%29
J+=+2%28S+-+5%29+-+4
Set J in the 1st equation equal to J in the 2nd equation
S+%2B+6+=+2%28S+-+5%29+-+4
S+%2B+6+=+2S+-+10+-+4
S+=+20 answer
J+=+S+%2B+6
J+=+20+%2B+6
J+=+26 answer
check answers
J+%2B+4+=+2%28S+-+5%29
26+%2B+4+=+2%2820+-+5%29
30+=+40+-+10
30+=+30
